Abstract (en)
A hydrocarbon composition, for example a lubricating oil electrical insulation oil or fuel oil, contains one or more heteroaromatic nitrogen compounds having the following general formula:wherein each X is N, CH or C-alkyl with at least one X being N; Y is N, CH or C-alkyl; R is H or CH<sub>2</sub>NR<sub>2</sub>" where each R" is H or alkyl of 1 to 20 carbons; R' is H, SR'" OR'" or NR<sub>2</sub>'" with each R'" being H or alkyl of 1 to 20 carbons. Preferably both X groups are nitrogen atoms and Y is CH. Suitable compounds include purine, 6-aminopurine and 8-azaadenine. The compounds impart antioxidant and/or metal deactivating and/or electrical insulating properties.
